Iminyl radicals are reactive intermediates that can be used for the construction of various valuable heterocycles. Herein, the electrochemical decarboxylation of α-imino-oxy acids for the generation of iminyl radicals has been accomplished under exogenous-oxidant- and metal-free conditions through the use of nBu4NBr as a mediator. The resulting iminyl radicals undergo intramolecular cyclization smoothly
亚胺基是反应性中间体,可用于构建各种有价值的杂环。在此,通过使用n Bu 4 NBr 作为介体,在无外源氧化剂和无金属条件下完成了用于产生亚胺基自由基的 α-亚氨基-羟基酸的电化学脱羧。所得亚胺基自由基与相邻的(杂)芳烃顺利进行分子内环化,得到一系列吲哚稠合的多环化合物。
